MLhs nodes have a special case for rest params which was previously incorrectly trying to emit soft indents outside of a breakable. We could have just made mlhs nodes breakables, but the parser interface for mlhs specifically is pretty awkward, so in this particular case I opted to leave it as-is and instead correctly pass the right special-case enum when inside of a multiassign.
(Reviewing this with hiding whitespace changes makes this a bit clearer)
Closes #416
